Well I have to RO/DI units and I want to combine them. Can anybody show me where to go to get visuals and if I have a booster pump will it affect its use?

I would T the input to both RODI and make sure you have more than 60 psi.
You are better doing dual RO membranes so you waste is reduced.

I will look into doing dual membrane but doesn't that reduce the life of the membrane?

BRS sells the 150gpd upgrade. I have one and waste water to Rodi is about 1:1.

As for membrane life, make sure you get a booster pump and provide >60psi

I think it would extend the lives of the membranes to do so. Depending on what units you are trying to combine, I would use unit one for maybe 2 sediments, 1st carbon stage, and go forward from there, and double stack the membranes. Booster pump will probably be necessary. There should be diagrams on Marine depots websites for similar units.

So I was reading even brs advice you can't have waste water above 300tds or else it shorten your membrane life considerably. I'll just hook up the membrane to have extra prefilter a and dual di cartilages.
